SPECIFICATION forming part of Letters Patent No. 315,400, dated April 7,1885.

Application filed September 10, i884. (No model.)

.70 all whom it may concern Be it known that I, THOMAS JEFFERSON FOWLER,of Birmingham, in the county of Jefferson and State of Alabama, haveinvented certain new and useful Improvements in Combined Cotton Sweeps,Choppers, and Dirters, of which the following is a full, clear, andexact description.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1' is a plan view of my improved machine, parts being brokenaway. Fig. 2 is a sectional side elevation of the same, taken throughthe broken line 00 m, Fig. 1.

The object of this invention is to provide machines constructed in sucha manner as to sweep or bar off the plants, chop them to a stand, anddirt or hill them at one passage along the row, and which shall besimple and inexpensive in construction, and readily adjusted andcontrolled.

The invention consists in the construction and arrangement of parts, aswill be hereinafter fully described and claimed.

A are the drive-wheels, one of which runs loosely upon and the other isrigidly attached to the axle B, so as to carry the said axle with it inits revolution. The axle B revolves in bearings attached to the frame 0,to the centers'of the front crossbars of which is attached the tongue D.

To hangers E, attached to the forward parts of the side bars of theframe 0, is journaled a shaft, F, the end parts of which are slottedlongitudinally to receive the standards G. The standards G areadjustably secured in the slots of the shaft F by bolts or othersuitable means, and to thelower ends of the said standards G are securedthe sweeps H,to bar off or sweep the sides of the row as the machine isv barring-off plows, is rigidly attached an arm,

drawn forward.

To the axle B is attached a gear-wheel, I, the teeth of which mesh intothe teeth of a smaller gear -wheel, J, attached to a short shaft, K.

The shaft K revolves in bearings attached to the frame 0, and to itsinner end is attached abeveled gear-wheel, L, theteeth of which meshinto the teeth of a beveled gear-wheel, H M, placed upon the upper partof the vertical shaft N, and resting upon a bracket, 0, atfl The shaft Nis contached to the frame 0. nected with the beveled gear-Wheel M by atongue and groove, so that the said shaft can be moved up and down whilebeing carried around by and with the said gear-wheel in its revolution.The lower'part of the shaft N revolves in bearings attached to the lowerend of a hanger, P, secured to the bracketO or to the frame 0.

To the lower end of the shaft N, or to ahead or hub attached to the saidend, are attached four (more or less) radial arms, Q, to the outer endsof which are attached or upon them are formed chopping-hoes or cuttersR.

The upper end of the chopper-shaft N is swiveled to a coupling, S, towhich is hinged the lower arm of an elbow-lever, T, which is fulcrumedto a support, U, attached to the frame 0, so that the shaft N and itsarms Q and cutters It can be raised and lowered to regulate the depth atwhich the said cutters work in the ground, and to raise the said cuttersaway from the ground when required.

The lever T, and with it the shaft N, arms Q, and cutters B, are held inanyposition into side bars of the frame 0 are attached hang ers W, towhich is journaled a shaft, X, the

end parts of which are slotted to receive the standards Y. The standardsY are secured adjustably to the shaft X by bolts or other suitablemeans, and to the lower ends of the said standards are attached thedirting-plows Z, the mold-boards or wings of which are so shaped as togive the desired form to the hills. i

To the shaft F, that carries the sweeps or a, to the outer end of whichis hinged the forward end of a bar, 6. The bar b extends back into sucha position that its rear end can be readily grasped by the driver fromhis seat to adjust the sweeps H. The lower edge of the rear part of thebar I) has recesses 0 formed in it to receive the edge of thecatch-plate (I, to hold the sweeps securely in any position into whichthey may be adjusted.

To the shaft X, that carries the dirtingplows, is rigidly attached anarm or lever, e, which extends along a catch-bar, f, by which the saidlever, and with it the shaft X, standards Y, and plows Z,are held in anyposition into which they may be adjusted.

g is a standard, the lower end of which is attached to the center of therear cross-bar of the frame 0, and to its upperendis attached the drivers seat h.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In a combined sweep, chopper, and dirter, the combination, with frame 0,the axle B,

having a gear-wheel, I, the shaft K, parallel with said axle, and havinga gear-wheel, J, meshing with the gear-wheel I and beveled gear L at itsinner end, the bracket 1?, depending from the frame 0, the verticalshaft N, loosely mounted therein,and provided with horizontal blades Q Ron its lower end, the beveled pinion M, connected to shaft N by a tongueand groove, and meshing with bevelgear L, the coupling S, swiveled tothe upper end of shaft N, the pivoted lever T, connected to saidswiveled coupling, and the rack V, adapted to be engaged by said lever'1, substantially as set forth.

THOMAS JEFFERSON FOWLER.
